IMPR OVElVIENT lN HARVESTING-MACHINES.

Specificationforming part of Letters Patent No. 5,l'74, dated June26,115+7.

To all whom it may concern:

Be it known that I, JOHN DUNLAP, of Walworth county, Territory ofWisconsin, have invented a new and useful Improvement in H arvesting-Machines; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference beinghad'to the annexed drawings, making a part of thisspecification,

in which-'- Z represents the endless cloth for conveying.

the cut heads of grain, &c., into box B.

c are belts for propelling endless cloth d. f

1 are belts for propelling the reels A.

g is an endless cloth for conveying heads of is driven alongside,ifrequired.

'h are the cutters or knives (which will be described hereinafter) forcutting the grain. i are arms for the support of the knives h. j is thelower part of the swinging brushes k.

1, represented in Fig. 3, (in dotted lines in Fig. 2,) is a piece of'wood placed close to the knives, to which is fastened either leather orbristles, whichever may be found to be the best for the purpose, whichforms a brush.

m represents rollers for endless cloth (I to revolve upon..

n is a piece of iron fastened to the lower part ofthefront part of themachine under No. 3,

. Fig. 1, for the purpose of placing a wheel between the two jaws n ofdifferent sizes, as may be required.

0 is the wheel.

12 is a flange placed and fastened upon the outside of maindriving-wheel G, for the purposle of receiving the belt f thereon todrive ree s.

q is the felly ofthe wheel 0; O, axle of the main wheel.

1' is a shaft, upon one end of which is placed u is a belt for thepurpose of propelling the endless cloth g.

'v is a piece of wood projecting from theside of B for end of shaft 1"to rest on.

w is an iron hinge, made in such a manner as represented, for the frontpart of the machine toswing upon.

w are the spokes of the wheel a.

v2 is a hook, which hooks into -l-', Fig. 1. Staple the other end of thehook or shank; is fastened to an upright piece of wood, t t, which pieceof wood serves for the lever a to pass into, where it is fastened bymeans of a pin at b", as represented.

A represents the reels.

B B are the boxes of the machine. -B"i.n Fig. 2 represents the after boxinside, in which the grain, 850., may fall'when required.

' D, Fig. 1, is the tongue by which the whole machine is propelled. Thehorses are hitched to the after end of the tongueD and pull with theirheads toward the machine, which is right before thein. v

No. 1, Fig. 1, represents the frame ofthe- 7 endless cloth g.

No. 2, Fig. 2, represents theswinging brush, which swings upon the shaftof the reels, for the purpose of cleaning and brushing any heads ofgrain off the knives that migh hang thereto.

E represents the main shafts of, the reels.

No. 3, Figs. 1 and'2, are points to gather the grain in such a mannerthat the knives of the reels inay cut all heads clea-r.--

The reels are made in two separate parts, as shown in the drawingsinFig. 2, at A,where it will be'seen that each works entirely independentof the other. The reason I have in constructing the reelsin. two partsis that a knife is very apt to spring when it is so longas to reach fromone side of the machine to the other, as theyare now constructed.Therefore, when the knife is not supported it will spring'and allow somegrain to remain uncut, and that in a broken state; but in arranging theknives in the manner that I have represented, they being shorter, do nots ring so much, and obviatea difficulty which is of great moment in amachine ofthis description. Figs. '3 and 6 give a view of the brushesand the knife passing between'them.

The steering apparatus.Fig. A5 No. 4 represents thehub of wheel; 5, thetire of wheels; 6, axle-trees, Fig. 5 5 Fig. 4: No. 7, pins passingthrough axle-tree 6, the other end fastened into piece 9, by which piece9 the axletrees 6 are turned by wheel 11, as shown in Fig. 5, No. 11.Fig. 4: N0. 10 is a piece to strengthen the frame upon which themovable-framef or piece 9 slides. Fig. 5:.No. 11 represents a wheel overthen stationary platform, by means of which the machine is to besteered. No.'12 are iron rods, which move. the piece9 at pleasure. No.13represents the upright shaft, which supports the wheel No. 11. Fig. 5:No. 14. represents the platform upon which a man or boy may stand todrive the horses and steer the machine.

Tile cutters or knives represented in Fig. 2, marked h. These knives aremade in any of the known forms-say about, three inches broad, square onthe edges, and about one inch thick, more-or less. as may be desired,

and ot'anylength tosuit the sizeof the mamany knives as six, and evenmore, if required. The knives also serve to bring .the standing grain incontact with the stationary knife F, Fig. 2, where the heads of grainare finally cut. Havingstated the use 0 rue knives, I will now proceedwith the operation of the same.

The reels A, as represented in the annexed drawings, Fig.1 representsthe position of the reels. The standing grain is gathered by the revolving reel-knives and brought against the stationary knife F, Fig. 2,where it is cut. The heads are thus cut from the standing grain withouttaking more straw than is necessary to obtain the heads. Al'ter'it iscut itis thrown upon the endless cloth (1, which carries it into 'hassing between the two brushes, one being a stationary brush and theother'swinging upon the shaft of the reel, (what'Imean by the swingingbrush isthat the swinging brush swings upon the shaft of the reels,) asrepre-- sented in Fig. 3, (marked K,) and in' Fig. 1, (marked indottedlities at 'K,) which is kept in that position by the weight g.This piece marked K and j form an obtuse angle, as re'psented in Fig. 1.

u The front part of the machine is raised or lowered by levers, asrepresented in Fig. 1, for the purpose of cutting either high or lowgrain.

the wheels placed underneath the front .partof the machine to regulatethe diiferent heights. By'placing diiferent-sized wheels in jaws n, Fig.1, the front part of themachine forward of the axle-tree of main wheelsupon which the whole machine rests) swings-upon a-hi'ng'e.

belt e, at the same time, in. passing under the cog-wheel t, puts 'it inmotion, and by \VlllGh" means it. turns the cogwheel S, which in Figs,

1 and 2 turns the shaft r, and finally propels endless cloth g, thussetting all parts of the machine in motion, performing all that isrequired of the machine. v The steering apparatus by which. the maohineis directed is represented in a top view at Fig. 4 and an end view'atFig. 5. (By referring-to those figures all of the different parts willbe seen.) N 0.12 shows the rods by means of which the piece 9 will'turnthe axle-tree .No. 6 by pin 7, this causing the wheels to be turned inany required direction by means of the wheel 11 and rods 12. Theaxle-trees are made in two separate parts, a s representedin Fig. 4..The steering apparatus is connected to the machine by the tongue, asrepresented in. Figs.

1 and 2, marked D. The horses are hitched a near to the steering."apparatus, pushing the machine before them.

What I claim as my inven tion,'and' ,desire tosecnre by Letters Patent,is

The swinging brush, as represented ,in the;
